  • Nov 03, 2012 · IntroductionI've heard tube amp from my friend. After researching i found that tube amp will produces smoother sound (aka digitaless sound in chinese). I was using Xonar essence STX that time. I thought Xonar Essence STX already produce the cleanest sound so i never think about changing to higher end DAC again. So, smoother sound, thats what i want. So, I went into the purchase of tube ...

  • Dec 01, 2017 · Buffers vs. Preamps. It’s important to note that this is not a preamp. It is merely a buffer. While a phono preamp boosts your turntable’s signal to a line level, a buffer merely runs the signal through a tube circuit. The volume knob does allow you to boost the volume a little.

  • The LM386 is a mono low voltage amplifier that can be used in a variety of applications. It can drive loads from 4 Ωto 32 Ω. The gain is internally set to 20 but it can be modified from 20 to 200 by placing a resistor and capacitor between pins 1 and 8. This device comes in three different 8-pin packages as PDIP, SOIC and VSSOP

This circuit will provide good results for almost any microphone pre-amplifier application. Incidentally, we can substitute a 2N2222A, 2N4401 or any general purpose NPN with a minimum hfe of 50 for the 2N3904 transistor used in this design example.
  • Pair the Vidar with Schiit's smaller tube preamp, the $349 Saga, and that pair together runs just over $1,000. Add a set of $500 ELAC Uni-Fi UB5 monitor speakers, and that would be a hell of a system! for much innovation in tube amp design. Following is one of Baxandall's contributions to tone circuitry: [NOTE: Use a DC-blocking cap to couple this circuit to a tube plate]. You've probably seen this circuit before in stereo amp schematics. A close look at this circuit will reveal that the bass and treble controls are almost opposite.
